- Here's a really nice example of a Td5 Defender 90, brought to Alive for our incredible GTB450 VNT turbo conversion and our super efficient Ultimate Intercooler, making it much more capable to drive!
We take you through the final stages of testing, from mounting the Defender onto our awesome MAHA MSR500 AWD Chassis Dyno, several power runs and then the final road test, all of which is (even by our standards!) pretty impressive!

DO you use solid mass flywheels for these setups? I already have a 2.5inch demmand exhaust. Is the 3inch more suited?
God I love the Td5 mines on 333k miles 33 mpg d2 manual. The new stuf won’t do the work for long enough
Just got back into a manual d2 after stints with a 110, d3 and l322 3.6. God ive missed it!
The old 5 pot with 333K 😮I've a FL1 Td4, but nowhere near that , just lagging way behind @57K 😁
@@pistonhedd it’s on 349313 miles now
That music during the dyno setup I think it needs a better beat possibly some more bass. I don’t know though what does stew say ?
Keeping it real at Alive ! Great video keep up the content !!
Stew did mention the muzak needed turning down a bit during the strap down. I’d already uploaded two edits of this video (10Gb each) and just ran out of time to make any more changes so we “sent it” as was and put that down to experience. We really appreciate your feedback though, thank you! 🤩

Enjoyed that 🤩 wouldn't mind getting one of those turbos and a live map. Currently running one of your hybrids and a map installed. She goes great too. I'm in the middle of doing some Allisport upgrades too. Great work folks 👍
Our GTB turbos are in a totally different league to anything available previously, so if you fancy giving it a refresh, it would be great to see you, and document the upgrade too! 🙂
Looks amazing, would you have any reservations doing this sort of work on a 220k miles example?
At that kind of mileage I’d expect you’ve already had to replace much of the drivetrain, and that’s usually where the weakness lies. The engines are generally good for it, if well maintained, but this is where a dyno test would come in useful, so we could assess how well it’s still running, before committing to the conversion.
There’s loads to consider and it’s best to give us a call to discuss your individual circumstances.
@@alivetuningltd thank you, i WILL pay you a visit soon, every video i see makes me more excited haha
Whats that in Kw's?
ive a alive stage 3 2,2 tdci and love it would love to put it on the dyno to see what it makes lol but it transforms it big time i had to change the clutch as it was sliping a wee bit it turned 53k the other day so ive only done about 5k with the map
I’ve had several 2.2 pumas trust me leave it stock you’ll have plenty to replace at 100,000 oil cooler, most of the sensors, the DPF will need removing and cleaning, the turbo will need replacing, the radiator will start leaking, the turbo hoses will wear through, break discs and pads all round, EGR valve, etc etc
How does the R380 enjoy the 500Nm?
In all seriousness, how much torque can the R380 tolerate? I was always of the understanding that the '380' in its title was how much torque it could handle.
I’d be interested to know how the rover rear axle stands up to the torque.
Wil a 110 fit on the Dyno?
Yes of course! The only consideration for those is the hight, if it’s been modified or has a roof rack, but even then they’ll usually squeeze into the dyno cell.
That engine wont be long of this world.
We’ll not tune a sick engine Mark, and you’d be surprised at how strong these engines are.
And results on a d2 automatic?
A D2 Auto with this turbo would need limiting to around 410Nm, but 200+hp is still attainable.
The way the GTB450 turbo picks up, works well on the Td5 Auto, reducing that lag effect you get on initial take off. This effect is more noticeable when the car is fitted with an uprated torque converter.
@alivetuningltd I have a ashcroft monster auto box in mine. That'll take it
I’m pretty sure they’re rated to 410Nm, but I’d recommend you contact Ashcroft just to be sure, then book it in and we’ll tune it to the maximum permissible torque, or more of you just want to send it! 😅
Now that is going to kill some driveshafts! Is the engine unopened - eg head porting, camshaft upgrade, valve springs, injectors ?? Lastly does your vgt controller allow the vanes to open at cruise ? :)
The engine (and shafts!) are completely stock and will hold this torque, if the vehicle is driven respectfully. This being such a clean example, shows that the owner truly cherishes their Defender, so it’s not been abused!
Our VNT control strategy ensures the vanes do indeed open under cruise and part throttle conditions, as requested by the control tables.
